Objective To explore the change of 25 hydroxyvitamin D level and its correlation with glucose metabolism and bone mineral density in elderly men with type 2 diabetes mellitus(T2DM).Methods Hospitalized 53 elderly male patients with T2DM (T2DM group) and 51 patients without T2DM (NDM group) were chosen.Blood.biochemical indexes and 25 hydroxyvitamin D level were measured.Bone mineral density of lumbar (L2_4),left proximal femur was measured by dual energy X-ray.Results The serum 25 hydroxyvitamin D level in T2DM group was lower than that in NDM group [(12.38 ±5.12)μg/L vs.(17.35 ± 5.52) μ g/L],and there was significant difference(P＜ 0.05).The serum 25 hydroxyvitamin D level was negatively associated with fasting blood glucose level and glycosylated hemoglobin (r =-0.225,-0.499,P ＜ 0.05).The serum 25 hydroxyvitamin D level was not associated with fasting insulin and homeostasis model insulin resistance index (r =-0.050,-0.082,P ＞ 0.05).The incidence of osteoporosis in T2DM group was higher than that in NDM group [30.19％(16/53) vs.11.76％(6/51)],and there was significant difference (P ＜0.05).The serum 25 hydroxyvitamin D level was positively associated with bone mineral density of femur neck,greater trochanter of femur and Ward triangle(r =0.773,0.762,0.812,P ＜ 0.05).The serum 25 hydroxyvitamin D level was not associated with bone mineral density of lumbar (L2_4)(r =0.116,P ＞ 0.05).Conclusions The prevalence of vitamin D deficiency is found in elderly men with T2DM.Vitamin D level can affect blood glucose control and increase the risk of the occurrence of osteoporosis.Therefore,T2DM patients,especially elderly patients,should be routine vitamin D testing.Vitamin D supplementation to the patients of vitamin D insufficiency in time may be beneficial to glucose metabohsm and the prevention and treatment of osteoporosis.

Objective To study pharmacodynamic changes of combined anesthesia with remifentanil at different target plasma concentrations and isoflurane at different minimal alveolar concentrations(MAC) in laparoscopic operations. Methods Forty-five patients with ASA status Ⅰ~Ⅱ,receiving selective laparoscopic cholecystectomy or laparoscopic oophorocystectomy,were included.The patients were randomly divided into three groups with 15 patients in each group.In the Group A,anesthesia was maintained with isoflurane inhalation at the MAC of 1.3;in the Group B,anesthesia was maintained with both isoflurane inhalation at the MAC of 0.6 and remifentanil target-controlled infusion at 4 ng/L;and in the Group C,anesthesia was maintained with both isoflurane inhalation at the MAC of 0.4 and remifentanil target-controlled infusion at 6 ng/L.Pharmacodynamic parameters and recovery characteristics,including bispectral index(BIS),heart rate variability(HRV),mean arterial pressure(MAP),heart rate(HR),time to additional administration of muscle relaxants,time to the recovery of spontaneous breathing,time to eye opening,time to endotracheal extubation,time to the recovery of orientation,and follow-up survey of "awareness during operation",were compared among the 3 groups.Results ①The BIS value was lower in the Group A than in the Group B and C at the time of pneumoperitoneum for 2 min and removal of the gallbladder or the ovarian cyst.The measures of HRV were higher in the Group A than in the Group B and C at the time of pneumoperitoneum for 2 min and removal of the gallbladder or the ovarian cyst.The measures of MAP and HR in the Group A were higher than those in the Group C at the time of pneumoperitoneum for 2 min,and were lower than those in the Group C at the time of the endotracheal extubation and the recovery of consciousness.②Either isoflurane inhalation at the MAC of 0.6 combined with remifentanil target-controlled infusion at 4 ng/L or isoflurane inhalation at the MAC of 0.4 combined with remifentanil target-controlled infusion at 6 ng/L provided satisfactory anesthetic maintenance.③Significantly shorter time to endotracheal extubation,to eye opening,and to the recovery of orientation were recorded in the Group B and C than in the Group A.Conclusions Anesthesia with target-controlled infusion of remifentanil combined with inhalation of isoflurane can be used for laparoscopic surgery.Pharmarcodynamic parameters and recovery characteristics show that combined use of remifentanil infusion at 4 ng/L and isoflurane inhalation at the MAC of 0.6 provides optimal anesthetic maintenance.

BackgroundHypoxia and hyperglycemia are the common causes of retinal neovascularization.In these states,H+ accumulates because of the elevated glycolysis and failure of retinal circulation,thus the retinas readily acidified. ObjectiveThe present study was to explore whether retinal acidosis independently regulates the production of vascular endothelial growth factor (VEGF) and pigment epithelium-derived factor (PEDF) and whether the regulation is related to oxidative stress.Methods The retinas from 2-week-old male SD rats were cultured with explant method in DMEM modulated by NaHCO3,and culture retinas were randomly divided into pH 7.2,6.8 and 6.5 groups for 24 hours.In addition,after 24 hours of culture as above described,retinas were washed using PBS two times and then followed by again culture in DMEM with pH 7.2 for another 24 hours.Also,antioxidant was added in different pH values of DMEM for culture as above described.The retinal samples were prepared for histopathological examination.The expressions of VEGF and PEDF proteins and their mRNA in retina tissue were detected by Western blot and fluorescence quantitative polymerase chain reaction (PCR) respectively.Results The retina showed the clear structure and morphology in pH 7.2 group and pH 6.8 group,but retinal vacuoles change was seen in pH 6.5 group after culture for 24 hours.No significant difference was seen in the expressing level of VEGF mRNA in retina between normal group and pH 7.2 group( 112％ ±11％ vs 100％ ±7％ ) (P=0.55),but those in pH 6.8 group and pH 6.5 group were significant increased in comparison with pH 7.2 group( 196％ ±43％ vs 100％ ±7％ ;251％ ±29％vs 100％ ±7％ )( P＜0.05 ).The expressing level of PEDF mRNA in retina in normal group was similar to that of pH7.2 group(86％ ±19％ vs 100％ ±33％) (P=0.64),but that in pH 6.5 group was significantly higher than pH 7.2 group( 230％ ±66％ vs 100％ ±33％ ) ( P＜0.05 ).The resemble results were found in the expressions of VEGF and PEDF protein.After pH reversion,the expressing levels of VEGF mRNA were 100％ ±13％,111％ ±9％,113％ ±9％ in pH 7.2 group,pH 6.8 group and pH 6.5 group respectively without significant difference among them (F=2.51,P=0.16).The expressing levels of PEDF mRNA were 100％ ±13％,110％ ±9％,108％ ±11％in different groups ( F =0.98,P =0.43 ).Under the presence of antioxidant,the expressing level of VEGF mRNA in pH 6.5 group increased in comparison with pH 7.2 group and pH 6.8 group ( P ＜ 0.05 ).The expressing levels of PEDF mRNA were significant different among pH 7.2 group( 100±31 )％,pH 6.8 group( 282±45 )％ and pH 6.5 group(480±117)％ (F=20.73,P=0.00). Conclusions VEGF can be induced by retinal acidification alone,which may be regulated by oxidative stress.Under the retinal acidification,antioxidants promote the expression of PEDF,suggesting that oxidative stress inhibits the production of PEDF.

Rhubarb is a perennial herb belonging to the genus Rheum L. (Polygonaceae). Rhei Radix et Rhizoma (rhubarb roots and rhizomes) is one of the most popular Chinese materia medica and has been widely used for strong laxative function. About 200 compounds with six different types of skeletons (anthraquinone, anthrone, stilbene, flavonoids, acylglucoside, and pyrone) have so far been isolated from eighteen species of the genus Rheum L. These constituents showed extensive pharmacological activities including cathartic, diuretic, anticancer, hepatoprotective, anti-inflammatory, and analgesic effects, as well as toxicological effects. Chemical fingerprint, LC-MS, and other analytical techniques have been used for the quality control of rhubarb. This comprehensive review summarizes the researches into the isolation, pharmacological activities, and phytochemical analysis reported since investigations began in the late 1940s. In addition, pharmacokinetic studies and clinical application of rhubarb are also discussed in present paper. © 2013 Tianjin Press of Chinese Herbal Medicines.

OBJECTIVETo observe the intervention of Dachengqi Granule (DG) on the apoptosis of small intestine smooth muscle cells (SMCs) in rats with multiple organ dysfunction syndrome (MODS) and its mechanisms.

METHODSHealthy 100 adult Wistar rats were randomly divided into the control group (n =20), the MODS model group (n =40), and the DG group (n =40).E. coli suspension was peritoneally injected to rats in the model group and the DG group to establish bacterial peritonitis induced MODS model. DG at 1 mL/100 g was administered by gastrogavage to rats of the DG group, twice daily for 3 successive days. Twenty-four hours after modeling, the proximal segment of intestine was taken and stained by using terminal-deoxynucleotidyl transferase mediated nick end labeling (TUNEL) and immunohistochemistry. Changes of apoptosis quantity of SMCs and the expression of Bcl-2 associated X protein (Bax), B cell lymphoma/leukemia-2 (Bcl-2) and cytochrome c protein (Cyt c) in mitochondrial apoptotic signaling pathway were observed.

RESULTSCompared with the control group, the apoptosis quantity of SMCs and the expression of Bax and Cyt c protein significantly increased, and the expression of Bcl-2 protein significantly decreased in the MODS model group (P <0.01). Compared with the MODS model group, the apoptosis quantity of SMCs and the expression of Bax and Cyt c proteins significantly decreased, and the expression of Bcl-2 protein significantly increased in the DG group (allP <0.01).

CONCLUSIONDG could inhibit apoptosis of SMCs through suppressing activation of mitochondrial apoptotic signaling pathway in intestinal SMCs, thus promoting the recovery of the gastrointestinal motility function in rats with MODS.

Treating different diseases with the same method is a unique original thinking in Chinese medicine, which embodies the spirit of treatment based on syndrome differentiation. We briefly reviewed the origin and development of this concept. We also reviewed that thinking of combination of disease and syndrome is its premise and foundation. We put forward the conditionality of diseases in treating different diseases with the same method by cutting-in modern biological basic researches, that is to say, one kind specific diseases or disease of one specific system. We emphasized the importance of diseases conditionality in treating different diseases with the same method, which was of great significance in studies on combination of disease and syndrome, correspondence of prescription and syndrome, and modern biological basic researches of treating different diseases with the same method.
